禁用 HttpClient 的日志记录消息答案

【问题标题】：Disable Logging Messages for HttpClient禁用 HttpClient 的日志记录消息
【发布时间】：2015-05-21 07:41:04
【问题描述】：

我正在使用 Selenium 使用 TestNG 框架自动化测试用例。它调用内部使用 HTTPClient 库的 WebDriver。在我的类路径中有多个日志记录 jar，即 - slf4j 和 log4j。

我已经尝试了这里写的几乎所有东西 - Disable HttpClient logging 比如创建一个log4j.properties文件，commons-logging.properties文件然后添加到classpath-src/java/main

所以我有 2 个问题 -

如何强制 HttpClient 使用特定的日志记录 jar（因为我没有添加任何有关日志记录 jar 的日志记录依赖项。它们会自动下载，因为其他一些依赖项可能在内部使用它。）

如何禁用 HttpClient 的不需要的调试消息。

SLF4J：类路径包含多个 SLF4J 绑定。 SLF4J：在 [jar:file:/C:/Users/~/.m2/repository/ch/qos/logback/logback-classic/1.0.7/logback-classic-1.0.7.jar!/org/ 中找到绑定slf4j/impl/StaticLoggerBinder.class] SLF4J：在 [jar:file:/C:/Users/~/.m2/repository/org/slf4j/slf4j-log4j12/1.6.1/slf4j-log4j12-1.6.1.jar!/org/slf4j/ 中找到绑定impl/StaticLoggerBinder.class] SLF4J：在 [jar:file:/C:/Users/~/.m2/repository/org/apache/activemq/activemq-all/5.6.0/activemq-all-5.6.0.jar!/org/ 中找到绑定slf4j/impl/StaticLoggerBinder.class] SLF4J：请参阅http://www.slf4j.org/codes.html#multiple_bindings 以获得解释。 SLF4J：实际绑定的类型为 [ch.qos.logback.classic.util.ContextSelectorStaticBinder] 在端口 3052 上启动 ChromeDriver (v2.9.248315)

【解决方案1】：

我有同样的问题，想隐藏这个日志：

13:00:17.577 [main] DEBUG org.apache.http.client.protocol.RequestAddCookies - CookieSpec selected: default
13:00:17.594 [main] DEBUG org.apache.http.client.protocol.RequestAuthCache - Auth cache not set in the context

我花了一些时间来寻找解决方案，我会尽量使其更通用。 httpclient 也可以使用自定义的日志框架。我在 spring rest api 项目中使用 httpclient。

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>

首先知道 httpclient 使用什么包装器进行日志记录。

1.1 让我成功的方法是添加 slf4j-nop 作为我项目的依赖项。通过添加依赖项 SLF4J 由于 multiple_bindings 引发了异常。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/francisc/.m2/repository/ch/qos/logback/logback-classic/1.1.8/logback-classic-1.1.8.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/francisc/.m2/repository/org/slf4j/slf4j-nop/1.7.22/slf4j-nop-1.7.22.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

1.2 第一个绑定是我们正在寻找的绑定。在我的例子中，jar 名称 logback-classic-1.1.8.jar 是我们需要查找配置以隐藏调试消息的包装器。

现在我们知道，我们正在使用 slf4j 和 Logback 记录器

2.1 将 logback.xml 添加到您的项目 (src/main/resources/logback.xml)。

2.2 配置示例，以启动并在以后根据需要进行配置。

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <logger name="deng" level="DEBUG"/>

  <root level="INFO">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

如果有不清楚的地方请评论。

我能找到的解决这个问题的方法是首先检查日志 jar 的来源。为此，您可以通过在 cmd 上运行以下命令来制作 Maven 依赖树 -

mvn dependency:tree  > test.txt

现在打开这个 text.txt 文件并检查正在下载的 Logger.jar。识别后，您可以使用 pom.xml 中的排除标记排除此 jar

    <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>log4j-over-slf4j</artifactId>
            </exclusion>
        </exclusions>
